A02:2021 – Cryptographic Failures | Complete Breakdown for Developers & Security Teams

Title: OWASP Top 10 A02:2021 – Cryptographic Failures | Complete Breakdown for Developers & Security Teams Description: Welcome to another episode in our OWASP Top 10 series! In this session, we explore A02:2021 – Cryptographic Failures, previously known as Sensitive Data Exposure. This video covers everything from the root causes of cryptographic risks to real-world exploitation techniques and how to implement strong, modern cryptographic controls. 🧩 Topics Covered: Overview of Cryptographic Failures Why “Sensitive Data Exposure” evolved into this category 29 CWE mappings including CWE-259, CWE-327, and CWE-331 Attack Scenarios: SQL injection, weak TLS, hash cracking Prevention Steps: Encryption best practices, HSTS, key rotation, strong algorithms 🔐 Best Practices Mentioned: Use TLS 1.2+ with Forward Secrecy Store passwords using bcrypt or Argon2 Replace MD5/SHA1 with SHA-256 or better Implement secure key management & avoid hardcoded secrets Validate certificates and avoid insecure crypto modes 📚 References: OWASP Application Security Verification Standard (ASVS) OWASP Cheat Sheets: Password Storage, Cryptographic Storage, HSTS, and TLS PCI-DSS, GDPR, and Data Protection Standards 📅 Video Duration: 3 Minutes 🎯 Ideal For: Developers, AppSec professionals, and cybersecurity learners #OWASP #CryptographicFailures #ApplicationSecurity #OWASPTop10 #Encryption #TLS #CyberAwareness #DataPrivacy #Infosec #DevSecOps
